The huge drop in prices allowed plenty of people to get one even if they needed a point and shoot, just because they could look more 'professional' (aka those only using automatic mode).
But there are just too many cases where DSLR are superior because of its manual mode (shutter speed, adaptability, wide-angle, ...)
I would say it's shared responsability.

Regarding the law it's a bit more complicated, owning one isn't a problem (Parrot is selling his stuff without troubles), but as for using it, you need to:
- have a direct visual on it
- no flight above 50 meters
as for a fly by video:
- Must be at least 15 Km between uav and closest airfield
- only allowed above unpopulated zone
- no flight above 50 meters
